Very-very big thank you!Here is what I come up with measuring the outside diameter of the barrels near the muzzle. The PP .22 and .32 measure the same: 0.450". With my old digital caliper that varies just a bit...might be 0.452 one time, 0.451 the next but the most accurate seems to be 0.450". The .380 measures 0.477". Same thing with that one, I don't have a high end dial caliper where I can apply prezackly the same amt of tightness each time but this should get you close. Oh, I could have done those in mm........but you can convert.
While I am interested in the possibility of conversion from one caliber to another and the compatibility of the barrels PP and PPK.Okay, Mammon, what are you up to (the world wonders)?
